ELECTRIC ENGINE.

SPECIFICATION forming part of Letters Patent No. 573,581, dated December22, 1896.

Application filed March 30, 1896. Serial No. 585,390. (No model.)

To (ZZZ whom it may concern.-

Be it known that I, ISAAC T. DYER, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, have 5invented a new and useful Improvement in Electric Engines, of which thefollowing is a specification.

The object of my invention is to provide a novel construction ofelectric motor for drivro ing an engine, for use in its purpose eitheralone or supplemental to the steam or other motive power employed.

Myimproved motor involves in its construction, as the essential parts, apair of solenoidmagnets having reciprocating cores connected with asuitably-fulcrumed lever which is operatively connected with the engineto drive it by the oscillatory movements of the lever produced by thelongitudinal reciprocation of the solenoid-cores under the control of anautomatic switch having a shifting-lever connection with the cut-offvalve of the engine, and which turns the current from an electricgenerator into the magnets alternately.

My improvement may be operatively applied to engines generally, but forthe sake of convenience I elect to describe its construction and mode ofoperation more particularly in connection with a locomotiveengine, andtherefore so illustrate it in the accompanying drawings, in which-Figure 1 is a view in side elevation of a locomotive-engine equippedwith my improvement; Fig. 2,an enlarged broken view,in front elevation,of the switch device, showing one of the magnets connected therewith;and Fig. 3 shows the switch device by a view in side elevation.

A and A are two solenoid-magnets having their cores B connected with alever C at one side of its fulcrum, the lever being connected at theopposite side of its fulcrum with the driver of the engine to be driven.

D is the switch device, the preferred construction of which is thatillustrated as comprising an inverted-U-shaped yoke r, supported in abox D and having pendulously suspended from its upper end a lever q,provided with lateral projectionsp and near its lower end, at which itterminates in a head a, embraced by one bifurcated end of alever m,fulcrumed between its extremities, and the opposite end of which issimilarly bifurcated to engage the head of a shifting-lever m. In theends of the yoke r, and in alinement with the projections 19 and o, aresupported, to be moved lengthwise with relation to stationary contacts Zand is, the contacts Z and k, each of which is spring-controlled, as byconfining about it a spring ,8 between its head and the adjacentyoke-arm. The contacts 7s and Z are connected by an insulated conductor2', with which one pole of a generator (such as a dynamo-electricmachine, indicated at E) is connected through the medium of a conductorZ. connected by an insulated conductor 2' which leads through abinding-post t, with one end of the magnet A, the other end of which maylead back to the opposite pole of the generator, and the contact Z issimilarly connected by an insulated conductor i which leads through abinding-post t, with one end of the magnet A, the other end of which maylead back to the opposite pole of the generator.

When the lever q is swung to bear with its projection 0 against thecontact 7a and force it against the contact/t, the circuit containingthe magnet A is closed over the wires 'Z and Z while the circuitcontaining the magnet A is broken at the separated contacts Z and Z.Thus the magnet A is energized and the magnet A is deenergized, causingthe former to suck its core B in one direction, thereby turning thelever C to actuate the driver of the engine accordingly. hen the lever Chas completed its stroke in the one direction, the shifting-lever m willhave been turned on its fulcrum to turn the lever m in the direction toswing the lever g at its pro jection 1" against the contact Z, therebyre-' leasing the contact k and permitting it to be retracted by therecoil of its spring .9 to break the circuit containing the magnet A,thus deenergizing the latter and forcing the contact Z against thecontact Z to close the circuit containing the magnet A, which is thusenergized to suck its core B in the opposite direction, with the effectof swinging the leverC in the direction to complete the revolution ofthe driver and of turning the shifting-lever m to swing the lever m inthe di- The contact 76 is rection to return the lever (1 at itsprojection 0 against the contact 7t" and thereby again produce closureoi. the circuit containing the magnet A in the manner already described.In the same way the lever q will be pendulously swung continuously, toalternately open and close the circuit containing each magnet of thesolenoid device, with the effect of longitudinallyreciprocating thecores ll and rocking the lever O to work the driver of the engine.

\Vhen my improvement is applied to a locomotive-engine l it may be usedupon the latter without in any way altering or impairing theconstruction. of the engine, and may form, as shown, a supplementalmotive power to the steam. In this application of my improvement twosets of the solenoid-magnets and their described connections with agenera-tor should be provided, each set being supported as shown of theone set in Fig. 1, namely, with the magnets A and A on supports 7t and7t, (which should be covered to protect the magnets, though to displaythem the covers are omitted,) secured to the side of the boiler, withthe automatic switch. device in its box D also secured to the side ofthe boiler and having the pendent lever in embracing at its lowerbifurcated end the head of the upper end of the lever on, which isfulcrumed at between its ends and en gages at its lower end the ordinary'rockii'ighead or shitting-link device g on a locomotivecngine, whilethe lever m is connected from its upper end with some driven part of theengine, as the rod f of the slide-valve, (not shown,) which controls, inthe usual man nor, the supply of steam from the steamchest G to oppositesides of the piston in the cylinder (3.. Then, as will be seen, thereciprocating motion of the rod f effects the rocking of the lever m torock the lever m and swing the switch-lever q. Moreover, on thelocomotive-engine the lever C of each set of my improved electricmechanism is fulerumed to a bearing (Z on the side of the boiler toengage at its upper slotted end a coupling 0, (which may be oi. brass orinsulating material,) connecting the two solcnoidcores ll, which screwinto the coupling, and to engage at its lower slotted end the crossheadi), connected in the usual manner with the drivers of the engine. Thegenerator may be a dynamo (indicated at .lfl) supported on the tender1*", as shown, and driven by a steamengine, (indicated at ll,)to whichsteam.

is supplied from the dome I of the boiler, or

it may be a set of storage batteries (indicated at E) and suit-ablyconnected in the circuits containing the solenoid-magnets and switchdevices I), or the current maybe taken in the ordinary manner from anoverhead live wire (indicated at E or underground wire through themedium of a trolley, (indicated at H In the application of myimprovement to any engine it should include in the line 1:,

leading from the generator to the switch. .1), a cut-out switch K, ofordinary or any suitable construction, and a graduating-switch device L,which may be like that commoi'ily employed on trolley-cars.
